Should we now debate the number of Demons (Maxwell's subset only), capable of dancing on the point of a needle?

While the Copenhagen interpretation of quantum theory, results in exactly the same mathematical projections as the Many-World's interpretation, it makes use the somewhat arbitrary/mystical concept that quantum wave-functions collapse when observed. Here it note that when one writes the quantum wave-function equations for the universe there are no terms for time; which offers still an alternate interpretation for a theory of everything, ToE (besides the Copenhagen & Many-World's) that the emergent human interpretation of time is actually a comparison of a smaller subset of the holographic universe to an associated incrementally larger subset of the holographic universe.
In this ToE interpretation, the information contained within, and forming, the universe is created by free will interacting with other free will (rather than free will being an emergent property as in the Many-World's interpretation). In this ToE interpretation the meaning of life would be to expand one's time horizon until one is "one-with-everything", thereby ending the illusions of time & space and maximizing one's compassion & interconnectedness. Furthermore, the hierarchy of levels creates the illusions of time & space by restricting one's understanding of the whole to a smaller subset of the holographic universe. Therefore, in this ToE interpretation of how the universe works, it is required in life to advance from the tyranny of small decisions associated with lower level subsets into the daylight of a more holistic world, using Maxwell's Daemon as an analogy for the work required from Shannon information theory to reduce entropy.

http://www.scientificamerican.com/article/what-einstein-really-thought-about-quantum-mechanics/Extract: ""I, at any rate, am convinced that He is not playing at dice." Albert Einstein wrote to a colleague in 1926. Repeated over the years, his sound bite became the quintessential put-down of quantum mechanics and its embrace of randomness.
Close examination, though, reveals that Einstein did not reject quantum mechanics or its indeterminism, although he did think – solid scientific reasons – that the randomness could not be a fundamental feature of nature.
Today many philosophers argue that physics is both indeterministic and deterministic, depending on the level of reality being considered.
This view dissolves the much debated dilemma between determinism and free will. Even if everything that particles do is preordained, the choices we make can be completely open because the low-level laws governing particles are not the same as the high-level laws governing human consciousness.

To be sure, List's arguments do not explain free will fully. The hierarchy of levels opens up space for free will by separating psychology from physics and giving us the opportunity to do the unexpected. But we have to seize the opportunity. If, for example, we made every decision on a coin toss, that would still count as macroindeterminism but would hardly qualify as free will in any meaningful sense. Some people's decision making may be so debilitated that they cannot be said to act freely.
This way of thinking about determinism also makes sense of an interpretation of quantum theory that developed in the years after Einstein's death in 1955: the many-worlds interpretation.

"There is not true randomness in the cosmos, but things can appear random in the eye of the beholder," says cosmologist Max Tegmark of the Massachusetts Institute of Technology, a prominent proponent of this view. "The randomness reflects your inability to self-locate."
That is very similar to saying that a die or brain could be constructed from any one of countless atomic configurations. The configurations might be individually deterministic, but because we cannot know which one corresponds to our die or our brain, we have to think of the outcome as indeterministic. Thus, parallel universes are not some exotic idea out there in the cosmos. Our body and brain are little multiverses, and it is the multiplicity of possibility that endows us with freedom."
In this regards most people want free will to mean freedom for their egos to do whatever they want via magical thinking; when in actuality free will means no ego, no soul, no magic thinking, only work via Maxwell's Daemons to reduce entropy via Shannon's information theory.
